“另类”谐波电流超标的研究

Study On The 'Special' Over-Criterion Harmonic Current

"另类"谐波电流超标是测试时并没有明显谐波源负荷运行.却存在谐波超标的现象。通过对"另类"电流超标的典型案例的实测结果分析.结合仿真分析阐明其谐波超标的机理,提出解决问题的方法,对提高谐波管理水平以及我国谐波国家标准修订工作有参考价值。

＇Special＇ over-criterion harmonic current appears when harmonic current is over-criterion, but no prominent harmonic source in the system could be found in the testing. Through the analysis on testing result of typical cases of over-criterion harmonic current and taking simulation analysis into account to explain the cause of them, this paper puts forword solutions which would benefit the harmonic management and the revising work of harmonic national standard.
